| 摘 要： | 提出潜艇碰撞问题,对其碰撞特征进行分析,并针对某型潜艇舯部典型结构的撞击极限强度特性进行数值计算,结果表明由于准静压载荷的附连耦合作用,随着静水压力的增加,潜艇舯部耐压壳体结构的防撞能力大幅下降,而耐压壳体内部的平台和舱壁结构能有效提高壳体结构的横向失稳临界应力,改善潜艇结构的径向耐撞能力.

| Abstract: | The problem of submarine collision is put forward of which the characteristics are discussed. Then, the characteristic of collision strength for a certain type submarine structure is numerical analyzed. The calculation results show that along with the water pressure increasing the collision resistance ability is down and the reinforced structure, such as flat and bulkhead, leads the flexure resistance to increase. And those inner structure can improve the radial collision resistance ability for submarine structure under transverse impact loading. |
